PS: A curious thing...
Her new machine came with an Office 2007 CD case, with the hologram and C of A etc - but no CD! There was a label saying that if you bought the backup CD, you could put it in this case. We had a debate about why the CD wasn't included, and decided it was to stop customers selling on the CD.
She asked the shop if they'd like the 2007 CD case back. They offered her a price that she agreed appropriately reflected the value of Office 2007
